Research And Design Of Can-based Remote Control System Of Marine Main Engine

The remote control system of marine engine is the kernel of ship-automation system.As computer technology and fieldbus technology has been increasing rapidly, many new technologies are used in the field of ship automation.At the same time,our country's shipbuilding industry is increasing fast.Ship automation made great progress.The control system based on fieldbus became trend in the field of ship automation.In this article,the control system of marine engine based on the CAN bus is the object of research.It established the design of the control system,finished the hardware design and software design of intelligent nodes.The ARM LPC2292 is MCU in the intelligent node.This control system includes device level,central control room and bridge level.The three nodes realize local control and remote control.The control system based on dual CANBUS ensures the reliability and real time of the data communications.According to the function demands of marine engine and principle of signal collection,this article designed the CAN network that can achieve Control system 'function of marine engine.This article analyses the technology of CANBUS,and make use of CAN bus for the control system of marine engine,and then discuss the dual CANBUS.The physical part of CANBUS is redundancy.The part is consisted of two set of network media,driver and controller.It is used to provide alternative functional channels in case of failure.This design meets reliable requirements of data transmission.The design of intelligent node includes hardware design and software design.The hardware is consisted of peripheral circuits of LPC2292.Including CANBUS interface circuit.Software design includes the design of communication among the nodes and the design of application of marine engine.This chapter makes communication protocol of CAN,and finish the program of the initialization and design the program of data communication.In order to improve stability and security of intelligent node,this article takes some measures for anti-jamming and anti-corrosion.At last this article make use of VB 6.0 to achieve program that can show states of marine engine.After experiment,the communication among PC and intelligent nodes is achieved.
